Myopia (Nearsightedness)

Myopia, or nearsightedness, is the condition of the eye in which images are formed in front of the retina, resulting in a blurred image. This occurs when the eye is relatively too long or the refractive powers of the cornea and lens of the eye are relatively too strong. Myopia usually begins in childhood, and progressively worsens until adulthood is achieved, usually about 18 to 21 years of age.
